They are very young, nice kids, who have started from a pure aws standpoint. They started with AWS tutorials. These tutorials did not teach the full unix environment. The gaps in their knowledge is like the grande canyon. If they just read the O'reilly book on linux: http://shop.oreilly.com/product/9780596154493.do. they would be miles ahead. But, their only interest is docker/kubernetes. Those technologies are great, but, they simply have massive gaps in their knowledge of the fundementals. They don't seem to like reading technical books from cover to cover. So they just read tutorials far enough to get the system started. Then they cut/paste from stackoverflow when problems arise. If that does not work, they blame the tools ("couched is too slow!"). Again, its not their fault, just the new dev culture. I freely admit I am an old fogey.
